This invention relates to a reading glass. Heretofore, in using readingglasses, several adjustments had to be observed and kept upsimultaneously, namely, proper distance 6 of the lens from the print,proper position of the lens and the observer with reference to theavailable source of light, such as window or lamp, in order to avoidshadow of the lens and patches of varying illumination on the print dueto dis rsed images of the source of 1i ht, and re ected images of thesource of light from the surfaces of the lens. v

Since the field of vision is limited, in reading, the position of thelens .has to be continually shifted andit was inconvenient and fatiguingto keep up the necessary adjustment; furthermore, there are oftenconditions where sufficient light is not available or the conditions ofillumination are adverse to the adjustment necessary for the convenientuse of the reading glass, for instance, in consulting telephonedirectories, books on commercial ratings or other works of reference.

This invention does away with the enumerated difficulties by obviatingthe necessity of focussing and positioning for illumi- Among the otherobjects are to provide a reading glass having means to sup ort the sameat the proper distance from t e magnified object, to properly light theobject to be magnified, to provide a lighting unit have cell or from ahouse current. Referring to the drawings: Figu I bodymg the principlesof my invention.

Collar 2 has turned over rim 5 which meshes withcorresponding rim 6 on neck 3 to. prevent accidental withdrawal of neck3. Adjacent the base of body portion 1 is an'opening 7 having a screwthreaded neck 8 to receive the screw threaded end 8' of container 9.Within container 9 is lamp 10, threaded into socket 11 which has abushing 12 passing through ahole 13 in the end of container 9. The endofbushing 12 carried a'nut 13% hold the socket 11 to the end of container9. An asbestos cover 14 or other heat transmission resisting materialcovers' container 9. Openings 15 permit the lugs 16 of the socket switchto protrude in order that the li ht may be turned on or off. In the use0 the house current I have found that ventilation is essential toprevent heating of the body portion 1. Ports 19' in the container 9permit air to emerge from container 9 and body portion 1 around the edgeof collar 18 adjacent body .portion 1. About the base of body portion 1,I provide ports 19. Body portion 1 has its lower edge 20 turned up tocover ports 19 but the turned up edge 20 is not in contact with bodyportion 1 to permit air to enter ports 19 and pass out of ports 17around edge of collar 90 18. Such circulation of air cools the containerhandle 9 and body portion 1. The,

height of body portion 1 containing lens 4' is less than the focallength of the lens used.

In the modified form the usual flashlight 21 is adapted to screw intoneck 8" after the lens has been removed from flashlight 21. The modifiedbody portion 1' has been shown having a square-shape to permit of thedelessen the eyestrain to the user and permits reading in a dimlylighted room.

What I claim is 1. A device of the kind described including an openbottomed body having a lower portion provided with a lateral openingadjacent the bottom end of the body, said body having its inner surfacearranged to reflect I and diffuse light entering said lateral opening, alam ousing extending from said opening, a amp in said housing, and alens closin the upper end of the body.
